<#
.SYNOPSIS
    Compares two versions and find whether they're equal, or one is newer than the other.
 
.DESCRIPTION
    The Compare-SemVerVersion allows the comparison of SemVer 2.0 versions (including prerelease identifiers)
    as documented on semver.org
    The result will be = if the versions are equivalent, > if the reference version takes precedence, or < if the
    difference version wins.
 
.PARAMETER ReferenceVersion
    The string version you would like to test.
 
.PARAMETER DifferenceVersion
    The other string version you would like to compare agains the reference.
 
.EXAMPLE
    Compare-SemVerVersion -ReferenceVersion '0.2.3.546-alpha.201+01012018' -DifferenceVersion '0.2.3.546-alpha.200'
    # >
    Compare-SemVerVersion -ReferenceVersion '0.2.3.546-alpha.201+01012018' -DifferenceVersion '0.2.3.546-alpha.202'
    # <
 
.EXAMPLE
    Compare-SemVerVersion -ReferenceVersion '0.2.3.546-alpha.201+01012018' -DifferenceVersion '0.2.3.546-alpha.201+01012015'
    # =
 
.NOTES
    Worth noting that the documentaion of SemVer versions should follow this logic (from semver.org)
    1.0.0-alpha < 1.0.0-alpha.1 < 1.0.0-alpha.beta < 1.0.0-beta < 1.0.0-beta.2 < 1.0.0-beta.11 < 1.0.0-rc.1 < 1.0.0.

.SYNOPSIS
    Install the Chocolatey Software from a URL to download the binary from.
 
.DESCRIPTION
    Install Chocolatey Software either from a fixed URL where the chocolatey nupkg is stored,
    or from the url of a NuGet feed containing the Chocolatey Package.
    A version can be specified to lookup the Package feed for a specific version, and install it.
    A proxy URL and credential can be specified to fetch the Chocolatey package, or the proxy configuration
    can be ignored.
 
.PARAMETER ChocolateyPackageUrl
    Exact URL of the chocolatey package. This can be an HTTP server, a network or local path.
    This must be the .nupkg package as downloadable from here: https://chocolatey.org/packages/chocolatey
 
.PARAMETER PackageFeedUrl
    Url of the NuGet Feed API to use for looking up the latest version of Chocolatey (available on that feed).
    This is also used when searching for a specific version, doing a lookup via an Odata filter.
 
.PARAMETER Version
    Version to install if you want to be specific, this is the way to Install a pre-release version, as when not specified,
    the latest non-prerelease version is looked up from the feed defined in PackageFeedUrl.
 
.PARAMETER ChocoTempDir
    The temporary folder to extract the Chocolatey Binaries during install. This does not set the Chocolatey Cache dir.
 
.PARAMETER ProxyLocation
    Proxy url to use when downloading the Chocolatey Package for installation.
 
.PARAMETER ProxyCredential
    Credential to authenticate to the proxy, if not specified but the ProxyLocation is set, an attempt
    to use the Cached credential will be made.
 
.PARAMETER IgnoreProxy
    Ensure the proxy is bypassed when downloading the Chocolatey Package from the URL.
 
.PARAMETER InstallationDirectory
    Set the Installation Directory for Chocolatey, by creating the Environment Variable. This will persist after the installation.
 
.EXAMPLE
    Install latest chocolatey software from the Community repository (non pre-release version)
    Install-ChocolateySoftware
 
.EXAMPLE
    Install latest chocolatey software from a custom internal feed
    Install-ChocolateySoftware -PackageFeedUrl https://proget.mycorp.local/nuget/Choco

.SYNOPSIS
    Register a new Chocolatey source or edit an existing one.
 
.DESCRIPTION
    Chocolatey will allow you to interact with sources.
    You can register a new source, whether internal or external with some source
    specific settings such as proxy.
 
.PARAMETER Name
    Name - the name of the source. Required with some actions. Defaults to empty.
 
.PARAMETER Source
    Source - The source. This can be a folder/file share or an http location.
    If it is a url, it will be a location you can go to in a browser and
    it returns OData with something that says Packages in the browser,
    similar to what you see when you go to https://chocolatey.org/api/v2/.
    Defaults to empty.
 
.PARAMETER Disabled
    Allow the source to be registered but disabled.
 
.PARAMETER BypassProxy
    Bypass Proxy - Should this source explicitly bypass any explicitly or
    system configured proxies? Defaults to false. Available in 0.10.4+.
 
.PARAMETER SelfService
    Allow Self-Service - Should this source be allowed to be used with self-
    service? Requires business edition (v1.10.0+) with feature
    'useBackgroundServiceWithSelfServiceSourcesOnly' turned on. Defaults to
    false. Available in 0.10.4+.
 
.PARAMETER Priority
    Priority - The priority order of this source as compared to other
    sources, lower is better. Defaults to 0 (no priority). All priorities
    above 0 will be evaluated first, then zero-based values will be
    evaluated in config file order. Available in 0.9.9.9+.
 
.PARAMETER Credential
    Credential used with authenticated feeds. Defaults to empty.
 
.PARAMETER Force
    Force - force the behavior. Do not use force during normal operation -
    it subverts some of the smart behavior for commands.
 
.PARAMETER CacheLocation
    CacheLocation - Location for download cache, defaults to %TEMP% or value
    in chocolatey.config file.
 
.PARAMETER NoProgress
    Do Not Show Progress - Do not show download progress percentages.
    Available in 0.10.4+.
 
.PARAMETER KeyUser
    API Key User for the source being registered.
 
.PARAMETER Key

.PARAMETER Name
    Name - the name of the source to find for comparison.
 
.PARAMETER Source
    Source - The source. This can be a folder/file share or an http location.
    If it is a url, it will be a location you can go to in a browser and

.PARAMETER Priority
    Priority - The priority order of this source as compared to other
    sources, lower is better. Defaults to 0 (no priority). All priorities
    above 0 will be evaluated first, then zero-based values will be
    evaluated in config file order. Available in 0.9.9.9+.
 
.PARAMETER Credential
    Validate Credential used with authenticated feeds.
 
.PARAMETER KeyUser
    API Key User for the registered source.
 
.PARAMETER Key

.PARAMETER Credential
    Credential used with authenticated feeds. Defaults to empty.
 
.PARAMETER Force
    Force - force the behavior. Do not use force during normal operation -
